    What Is a Ball Turning Gland?

    A ball turning gland is a mechanical sealing solution used in rotating dredging pipelines. It allows controlled rotation of the pipe while maintaining a pressure-tight seal — essential for reliable dredging operations.

    Turning glands are typically applied where:

    • Pipelines must rotate relative to fixed sections
    • Pressure and abrasive materials are involved
    • Leakage or downtime is not an option

    Designed for Dredging Applications

    Straatman turning glands are engineered specifically for dredging environments, where sand, slurry, pressure and continuous movement put systems under constant stress.

    Typical applications of turning glands:

    • Dredging pipelines with rotational movement
    • Hopper dredgers, cutter dredgers and stationary dredging installations
    • Newbuild and retrofit dredging systems

    Key Features of our turning glands

    Reliable sealing under rotation
    Maintains pressure integrity during continuous or intermittent rotation.
    Heavy-duty construction
    Designed for abrasive media and harsh marine conditions.
    Low friction, controlled movement
    Minimises wear and extends service life.
